Abstract: A method to measure response time of a chain of events that is a set of individual events includes identifying a chain of events comprising a set of events for which the response time is to be measured; identifying a sequence for processing of said events; tracking the processing of each of the identified events in said sequence; waiting until all the identified events are executed in said sequence; and calculating response time of said chain of events by marking beginning of execution of first event and the end of execution of last event, after making sure that each of said events is considered executed only when the preceding event in said sequence is executed.
